Tropical Depression: An organized system of clouds and thunderstorms with a defined surface circulation and maximum sustained winds of 38 mph or less.

Tropical Storm: An organized system of strong thunderstorms with a defined surface circulation and maximum sustained winds of 39 to 73 mph.

Storm Surge: Storm surge is a large dome of water that sweeps across the coastline. The surge is greatest along and to the right of where the hurricane's eye makes landfill and occurs generally where the highest wind speeds are located in the eye wall. Storm surge poses the greatest threat to life and property for coastal communities. Ninety percent of hurricane fatalities are related to storm surge flooding. Read NOAA's explanation of them.
